The approach


About the installation

188,000square feet of bunkers (4.3 acres)

“We knew the bunkers needed to be relined, and we wanted a liner that could perform at the highest level, no matter the season” Thornsbury  said. “When we researched the options, it became clear to us that Capillary Concrete had a superior bunker product and was the one we wanted to use.”

“We have large, very elaborate bunkers with steep faces,” he said. “Over the years, as with all aging bunker sand, it had lost its original color, the consistency to move water, and the playability was negatively affected, especially during the dry summer months or excessive rain events. With this project, we wanted to restore the sand to its original color, ensure the health of the drainage system, and most importantly, install a bunker liner that was going to last for many years to come.”

After completion of the project, “we had our first major rain event of the season, producing six inches of rain in less than three days, which for us in Central California, is welcomed and unusual. Not one speck of sand moved in our newly completed bunkers. The team was relieved to see they didn’t require any repairs after such a heavy rain event and kept the sand shovels in the shop that morning. It’s a testimony to the Capillary Bunkers product.”
